ANCHOR-ROD.

Specification of Letters Patent.

Patented Aug. eaters.

Application filed June 4, 1917. Serial No. 172,739.

To all whom it may concern:

Be it known that l[, WILLIAM R. BRASHEAR, citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Anchor-Rods, of whichthe following is a specification.

My invention -relates to land anchors and more particularly to guy orstrut anchors for telephone and telegraph poles, fence posts, bridgeanchors and other analogous devices employing a buried support. Theinvention relates more especially to a detachable anchor rodparticularly applicable to temporary structuresas for instance, temporary telephone and telegraph lines, fences and derricks or elevatorsupports.

The object of the invention is to simplify the structure as well as themeans and mode of operation of land anchors whereby they will not onlybe cheapened in construction, but will be more eficient in use, positivein operation, easily and quickly attached and detached, and unlikely toget out of repair.

A further object. of the invention is to provide an improved form ofanchor rod engaging member from which the rod may be readily and quicklydisengaged without 13%8 necessity of digging up the buried anc or.

With the above primary and other incidental objects in view as will morefully appear in the specification, the invention consists of thefeatures of construction, the parts and combinations thereof and themode of operation or their equivalents, as hereinafter described and setforth in the claims.

Referring to the drawings, Figure 1 is a sectional side elevation of theassembled land anchor forming the subject matter hereof, in operativeposition. v Fig. 2 is a detail side elevation, partly in section, of theanchor rod and the engagement plate, showing in dotted lines therelative movement of the rod to efi'ect the release of same from theplate. Fig. 3 is a detail perspective view of the engagement plate. Fig.4 is a fur ther modification.

Like parts are indicated by similar characters of reference throughoutthe several views. I

It is the present practice in telephone and telegraph construction, aswell as in the erection of derricks and like constructions to employ asa land anchor to which the ends of the guys or strut cables areconnected, anchor rods having at their upper ends eyes or loops throughwhich the guys or struts are engaged and screw threaded at their lowerends. These anchor rods are extended through suitable holes in a log orlarge block of wood and are provided upon the protruding screw threadedend with a washer or collar and lock nuts. The expense of setting orburying such a land anchor is usually greater than the expense of theanchor rods themselves. The anchor rods themselves, however, aresufliciently valuable to warrant the recovery or salvaging of such rodsif it can be efi'ected without the necessity of digging the anchor up orunearthing it.

To enable the recovery of the anchor rod with minimum labor and expense,with a loss only of the engagement plate and the wood block known as thedead man, is one of the primary objects of the present invention.

Referring to the drawing, 1 is the anchor rod having at its upper endthe eye or loop 2 through which is engaged the guy or strut cable 8. Therod 1 extends through a transverse hole 4 in alog or block of wood 5technically known as the dead man. The rod. 1 is preferably providedwith a medial enlargement 6 substantially equal in diameter to the hole4 in the dead man. At its lower end this enlarged medial portion 6 isprovided with a tapered or conical extension 7 terminating in ashouldered conical head 8. The diameter of the head 8 is slightly lessthan that of the enlarged medial portion 6. Although the enlargedportion 6 is shown in the drawing somewhat extended and is thepreferable form, this enlargement may be of comparatively short extentconsisting substantially of only the tapered portion 7 as indicated at'FFig. 4.

with the head 8, the jaws may be slightly recessed as at 11 on theiradjacent ends. These notches or indentations in the ends of the jaws,however, are not essential. The engagement plate 9 is of comparativelyheavy material suitably proportioned to the strain to which the anchorrod is to be subjected. The engagement plate is preferably of wroughtiron, malleable iron or steel, although it may be of other material. Itis not desirable that it should possess a great degree of elasticity orspring, although the normal degree of elasticity of such metals notobjectionable. The head 8 of the anchor rod having been passed throughthe engagement plate, intermediate'the jaws 10, the latter are bent intoclose engagement with the neck 12 of the'anchor rod, beneath theshouldered head 8. This is best done by striking the jaws or tongues 10with a hammer or a sledge. It will be understood that the anchor rod isextended through the dead man and engaged with the engagement platebefore the parts are buried. The parts are then deeply and permanentlyburied.

When it is desired to disengage and remove the anchor rod 1, the guy orstrut cable 3 is disengaged and the anchor rod 1 driven longitudinallydownward by sledge hammer blows upon the upper exposed end. Thelongitudinal movement of the anchor rod 1 under the influence of suchhammer blows forces the tapered or conical portion 7 of the rod betweenthe jaws 10 of the engagement plate, thereby forcing said jaws open asindicated by dotted lines in Fig. 2. The tapered head 8 enables the rodto penetratemore easily togreater depth during the initial downwa'rdmovement of the anchor rod. The upper or largest diameter of the taper 7being. greater than the diameter of the head 8 forces the jaws 10 apartsuch distance that .upon the reversal of the direction of the anchor rod1, the

' head 8 may readily pass between said jaws and be drawn through thehole 4 in the dead man 5 and from-the earth. The withdrawal of the,anchor rod may be effected in any suitable manner or by any means.However, a convenient and efi'ective means is provided by a block andtackle connected at one end to the eye 2 and at its opposite end to anysuitable support or abutment.

While as before stated, the-enlargement of the anchor rod 1 may notnecessarily ex- .tend beyond the tapered portion 7, the extendedenlargement 6 is for the purpose of excluding dirt or gravel from-thehole 4 in the dead man, which might by becomin packed or locked thereininterfere with the withdrawal of the anchor rod;

By 'the construction heretofore described,

it will be understood that theanchorrod 1,

may be readily removed by first-forcing it downward to separate theengagement jaws 10 sufliciently to permit the shouldered head 8 to passbetween the jaws, and thenwithdead man 5 and the anchor plate 9 buriedin the ground.

From the above description it will be apparent that there is thusprovided a device of the character described, possessing the particularfeatures of advantage before enumerated a desirable but which obviouslyis susceptible of modification in its form, proportion, detailconstruction or arrange ment of parts, without departing from theprinciple involved or sacrificing any of its advantages.

While in order to comply with the statute, the invention has beendescribed in language more or less specific as to certain structuralfeatures, 'it is to be understood that the invention is not limited toany specific details, but that the means and construction hereindescribed comprise but one mode of putting the invention intoefiect, andthe invention is therefore claimed broadly in any of its possible formsor modifications within the scope of the appended claims.

Having thus described. my invention, I claim 1. In a land anchor, ananchor rod having anintegral terminal head, a longitudinally disposedcam surface adjacent to the head, an engagement plate having jawsadapted to engage said rod adjacent to the head, the cam surface uponsaid rod being brought into engagement with the jaws to forcesaid jawsapart a distance greater than the width of the head by a longitudinalmovement of the rod whereby the rodhead may be disen gaged from saidjaws.

2. In a land anchor, an anchor rod, a detent member normally limitingthe reciprocatory movement of the rod in one direction,

and means for disengaging the rod from ing position by the engagement ofsaid tapered portion upon a longitudinal movement of the rod.

4. In a land anchor, an anchor rod having a shoulder formed thereon, aninclined face g upon said rod extending laterally beyond the limit ofsaid shoulder, and a detent memupon a longitudinal movement of the rod.

5. In a. land anchor,.an anchor rod, a detent plate having a flexibleengagement 'ber adapted to be engaged with the shoulder but movabletherefrom by said inclined face tongue normally engaging with said rod,

and means for flexing said tongue out of engaging position by alongitudinal movement of the rod.

6. In a land anchor, an anchor rod, a detent plate having oppositelydisposed engagement tongues adapted to engage with said rod to limit itslongitudinal movement in one direction, and means for simultaneouslyflexing said tongues out of engaging positions by a longitudinalmovement of the rod in the opposite direction.

7. In a land anchor, an anchor rod, a detent plate having therein twosubstantially parallel spaced incisions connected medially by atransverse incision to form two oppositely disposed tongues betweenwhich the rod is extended, said tongues being adapted to normallyprevent the Withdrawal of the rod, and means for disengaging saidtongues from the rod by initially forcing the rod an additional distancethrough said detent plate, thereby permitting the withdrawal of the rod.

In testimony whereof I have hereunto set my hand this 24th day of May,A. D. 1917.
